我正在尝试使用eclipselink(2.4.0)和spring-data-jpa(1.1.0.RELEASE)的组合来实现解决方案。但是,每次我部署解决方案(Tomcat的7)时,我得到以下异常:Eclipselink&Spring Data
Caused by: java.lang.IllegalArgumentException: No [ManagedType] was found for
the key class [com.acme.domain.entities.User] in the Metamodel - please
verify that the [Managed] class was referenced in persistence.xml using a
specific <class>com.acme.domain.entities.User</class> property or a global
<exclude-unlisted-classes>false</exclude-unlisted-classes> element.
它出现时库自动装配发生(代码下面的示例)发生:
服务类
@Component
public class UserDataService {
@Autowired
private UserRepository userRepository;
...
}
实体类
package com.acme.domain.entities;
...
@Entity
@Table(name = "users")
public class User implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "user_id")
private Integer id;
...
}
的persistence.xml
<persistence-unit name="default" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>com.acme.domain.entities.User</class>
...
</persistence-unit>
这可能是由于spring和eclipselink之间的一些冲突?
UPDATE:
堆栈跟踪...

您能否包含完整的堆栈跟踪。它只是元模型还是其他的东西不起作用? – James 2012-07-31 14:15:51
我已经添加了上面的堆栈跟踪 - 所有工作都很好,只要我添加自己的存储库实现,即难题的eclipselink部分是好的。只要我将spring-data-jpa添加到混音中,就会发生上述情况...... – NubieJ 2012-07-31 15:12:09
在独立应用程序中出现完全相同的问题,是否有更新? – JBA 2014-03-05 11:37:47
